Abstract
In recent years, Augmentative and Alternative Communication (AAC) has became popular as an effective approach among the language intervention practices. At the same time, AAC has developed as an interdisciplinary or multidisciplinary field of clinical and research effort which provides individuals with severe communication disorders with comprehensive support and services in terms of medical, welfare, and educational concerns. Based upon the two articles by Remington (1994) and Mirenda (1997), this paper introduced research trends of the behavior analytic approach which has been intended for theoritical investigation and development of intervention strategies, in relation to the use of AAC options. Implications for future requirement in intervention practices of AAC are discussed.
